PIPE-HANGER.

Specification of Letters Patent.

Application filed September 16, 1909. Serial No. 518,110.

To all whom 'it may concern:

Be it known that I, ROBERT C. HUNTER, a citizen of the United States, residing at Brightwood, District of Columbia, have invented certain new and useful Improvements in Pipe-Hangers; and I do declare the following to be a full, clear, and exact description of the invention, such as-will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

This invention relates to the class of pipe hangers but is more particularly designed to be used in connection with the running of gas pipe and the like in buildings.

It is the usual practice in running gas pipe to connectwith the main gas line pipe a short pi e which by means of an ell passes downwar ly between the joist of a building through the ceiling to which pipe the gas chandelier or fixture is connected. It is essential that this short pipe be hung or stayed in such a manner that it will be absolutely rigid and will not allow the chandelier or fixture any vertical or lateral movement.

This invention consists in providing a pipe hanger of two separate pieces, the same being preferably made of thin sheet metal and stamped out in the form and shape as will be hereinafter fully described.

Referring to the accompanying drawing:

Figure 1 is a perspective view illustrating my invention in operative position. Fig. 2 is a transverse sectional view taken through two joist showing the upper member of the pipe hanger in position thereon and the floor of the building on the hanger, and Fig. 3 is a top plan view ofthe upper member of the ban er.-

Like numerals of reference indicate the same parts throughout the several figures in which;

1 indicates the main line pipe, 2 the joist and 3 the short pipe leading from the main line pipe to the chandelier or other gas fixture. As the short pipe 3 leads from the main line pipe 1 at right angles thereto it is usual in plumbing and gas fitting to stay the outer end of the pipe 3 by means of blocks securely nailedto the joist. The operation of building these blocks properly to the joist to support and stay the plpe 3 takes considerable time and after the same has been accomplished the operation does not always result satisfactorily as the staying becomes loose and frequently allows the pipe 3 and chandelier a vertical as well as a transverse play or movement.

For the usual blocking and staying I employ a pipe hanger formed oftwo parts or members, theupper part or member being designated by the numeral 4 while 5 indicates the lower part or member. The upper part or member 4 is as shown in the drawing constructed preferably of thin sheet metal having aseries of recesses or notches 6 formed in the upper edge 7 of the member 4. It will be noted that these recesses or notches 6 extend from one end of the member 4 to ap roximately the center thereof, while the bal member is smooth. The member 4 is constructed in this mannerin order to cheapen the cost of manufacture as well as to strengthen the same for the reason that the notches or recesses 6 in half of the member 4 allow adjustment of the pipe 3 throughouthalf of the space between the joist 2; while by simply reversing the member 4 the same extent of adjustment can be secured throughout the other half of the space between the joist 2. By reason of this construction it is only necessary to recess or notch the member 4 throughout half its length as isat once apparent. The member 4 being constructed of thin sheet iron the ends 8 are given a quarter turn and are perforated to receive a nail 9, the ends 8 being flattened as shown the surfaces of which are in line with and parallel to the upper edge 7 of the member 4 as is clearly shown in Fig. 2. This quarter turn at each end of the member 4 causes the body of said member to present its edge to the weight and strain occasioned by the pipe 3 thus adding greatly to the strength and rigidity of the member 4 and making it possible to construct same out of very much lighter metal than could otherwise be employed.

The lower member 5 of the pipe hanger is constructed preferably of thin sheet metal having its. ends 10 bent upwardly at right angles to the body of the member 5 and perforated to receive a nail 11. It will be noted from Fig.1 that the member 5 is provided .with a series of perforations 12 throughout half its length, said perforations extending from the innerside of one of the joist to approximately the center of the member 5 thus afio-rding adjustment of the pipe 3 .Patented Feb. 15, 1910.

ance of the upper edge 7 of said 7 strength and rigidity to thesame.

It. will be noted that. as the upper member -t is firmly secured to the upper edge of the joist 2 and as the lower member 5 is rigidly secured to the lower portion of the joist 2 that. these members 4 and 5 besides acting in the capacity of a pipe hanger securely strengthen the two joistreventing same from spreading and twisting and largely assist in maintaining the said joist in their proper relative positions. It is also apparent that as the ends 8 and upper edge 7 of the upper member 4 are parallel, the floor which I have indicated by the reference numeral 13 in Fig. 2 rests snugly upon the upper section 4 and acts as a closure for the recesses or perforations t3 effectually locking the pipe 3 within the upper section 4.

Having thus described the several parts of my invention it is perfectly apparent that the upper section 4; effectually takes the weight of the pipe 3 as well as the weight of the chandelier or other gas fixture; While the lower member 5 of the hanger through which the pipe 3 passes effectually holds the pipe against any lateral n'iovement to such an extent that when the chandelier or other gas fixture has been connected to the pipe the same is absolutely rigid;

Having thus fully described my invention what I claim as new and desire to secure by Letters Patent of the United States, is

1. A pipe hanger for supporting the horizontal pipe and the vertical pipe of a pipe elbow comprising two parts orv members, the upper part or member being provided along its upper edge with a series of recesses or notches, the ends of said upper member being twisted a quarter turn and provided with a. perforation to receive a fastening, the ends of said upper member being designed to lie on the upper edges of two joist, the lower member having its ends turned at right angles thereto and designed to engage the lower portions of two joist, said lower member belng provided with a series of perforations through which a pipe is adapted to ass, the upper notched member being arranged to sup ort the horizontal pipe, the lower perforate member being arranged to guide the vertical pipe, the two members being in close roximity to each other and rigidly fastened to prevent relative movement.

2. A pipe hanger for supporting the horizontal pipe and the vertical pipe of a pipe elbow comprising an upper and a lower member, the upper member being adapted to be secured to the upper edges of two joist, the lower member being adapted to be secured to the lower portions of two joist at a point below the upper member, said members being in close proximity to each other and rigidly fastened to prevent relative movement, the upper member being provided with a series of notches or recesses to accommodate the horizontal pipe and the lower member being provided with a series of perforations through which the vertical pipe is adapted to pass.

3. A pipe hanger for supporting the horizontal pipe and the vertical pipe of a pipe elbow comprising an upper member and a lower member, said upper member being provided with a series of notches or recesses to accommodate and support the horizontal pipe, and the lower member being provided with a series of perforations through which the vertical pipe is adapted to pass, the said members being arranged in close proximity to each other and rigidly fastened to prevent relative movement.

In testimony whereof, I afiix my signature, in presence of two witnesses.
